喷墨打印墨水的色度学分析

通过对Canon ,EPSON ,HP ,LEXMARK四个著名品牌打印机原装彩色三原色墨水的光谱透射率测定及色度学分析 ,得到每一颜色的三刺激值、色度坐标 ,比较了这四个品牌墨水的三原色拼色的色域大小、彩度值、色相的主波长及补色波长。提出了三原色补色波长之间关系的一个经验公式 :λcompl,M 10 / 9(λcompl,Y) 10 ,及λcompl,M 9/ 10 (λcompl,C) - 2 0 ,发现这四个品牌墨水的三原色的补色波长与此公式有较好的适应性。

Chromaticity Analysis for Colorants in Dye-Based Ink-Jet Inks

For ink-jet color inks used for the well-known printers, taking Canon, EPSON, HEWLETT PACKARD and LEXMARK as samples, transmittances of the ink solutions were determined, and then the chromaticity analyses were made, in order to calculate the tristimulus values and the chromatic coordinate of each color sample. Also, the gamuts, chroma values, dominant wavelengths and complementary wavelengths were obtained by using the chromatic method for the samples. In this paper, an empirical formula was suggested for the relationship between the complementary wavelengths of the three primary colors: lambda compl, M approximately equal 10/9 (lambda compl, Y) + 10 and lambda compl, M approximately equal 10/9 (lambda compl, Y) - 20. It was found that the empirical formula is well suited for matching the complementary wavelengths of the three primary colors for ink sets of the samples studied.
